Chondrodysplasia punctata, tibial-metacarpal type in a 16 week fetus.

ultrasonography in a fetus at 16 weeks’ gestation. Generalized shortening of the long bones, with bowing of the femora and tibiae, a flat midface, small mouth, and micrognathia, were demonstrated. Radiologic findings of vertebral coronal clefts, shortened tibiae, elongated fibulae, and calcific stippling confirmed the diagnosis of CP-MT. Skeletal dysplasias are a heterogeneous group of bone growth disorders that result in an abnormal shape and size of the skeleton. CP-MT refers to a category of skeletal dysplasias with stippled calcification and abnormalities of vertebrae, long bones, and viscera. This report describes the ultrasonographic, radiographic, and pathologic findings in a fetus aborted during the second trimester of pregnancy because of a skeletal dysplasia. This fetus showed findings of CP-MT as described by Rittler and associates.1
